Upcoming Parity Violation Experiments and the New RTP Pockels Cell

Abstract:

A broad program of important parity-violation measurements in electron scattering from heavy nuclei will constrain nuclear structure models as well as search for new BSM physics. PREX and CREX are upcoming PVES experiments in Hall A which aim to map the weak charge distribution in nuclei, with implications for the equation of state of highly dense matter, neutron stars, and gravitational waves produced in neutron star collisions. MOLLER is another upcoming PVES experiment searching for new neutral currents, providing an unprecedented precision on the electron weak charge and electroweak mixing angle. One common crucial component of all these experiments is control of helicity correlated false asymmetries in the polarized electron beam. This talk will describe the development of the newly installed RTP Pockels cell system in the injector source which will enable this future generation of experiments. Recent measurements which achieved <30nm position differences in the injector with the RTP cell will also be shown.
